The utility model patent discloses an electric vehicle charger with a retractable wire. The electric vehicle charger includes a storage box, a winding wheel and a wire; one end of the wire is connected with the charger; the winding wheel is mounted in the storage box; a coil spring and a sliding ring are provided in the winding wheel; and the sliding ring has a conducting ring and a conducting strip. When the winding wheel is rotated, the conducting strip rotate synchronously with the winding wheel; and furthermore, when the conducting strip slides on an outer surface of the conducting ring, the conducting strip and the conducting ring are kept in electric contact. The electric vehicle charger further includes a pull-stop structure; the pull-stop structure includes a limiting gear and a latch; the latch selectively limits the limiting gear; and the limiting gear is an incomplete gear.

A fast-charging method is provided for rapidly charging an electric vehicle at a light-duty charging site comprising a residential dwelling or a small off-grid power station. The fast charging method incorporates an intermediate battery bank, or power buffer, that stores energy between EV charging cycles, then discharges the stored energy into the EV at a higher rate than the primary electric power source for the charging system. The power buffer thereby acts as a power multiplier that accelerates the rate of charge of an electric vehicle. Substantial power multiplication factors are possible at light-duty charging sites, resulting in large improvements in electric vehicle charging rates. The method may be applied using a number of primary power sources including AC from the utility grid, DC from photovoltaic panels, or power from other electric vehicle chargers (including both AC and DC electric vehicle chargers).
